The blockade, which also applies to Israeli ships, was launched "because of
the assault on the Ship to Gaza (flotilla), that we supported before they took
off ... and the blockade of the Gaza strip, which affects the civilian population," union spokesman Rolf Axelsson said.
The dock workers' protest is set to take place in all unionised Swedish ports, and is scheduled to and ends at midnight on June 29th.
Union chairman Björn A. Borg added the union called for an international investigation into the May 31st raid that killed nine pro-Palestinian activists.
He told AFP the dock workers believed Israel's easing of its Gaza blockade, announced on Sunday, was insufficient.
Eleven Swedes, including crime writer Henning Mankell, took part in the flotilla and were briefly taken into Israeli custody.
The Swedish Dock Workers Union original announced their intended blockade on June 2nd to take place from June 15th-24th but later announced an amendment to the dates in a statement dated June 11th.
